2020 JUN 29 (NewsRx) -- By a News Reporter-Staff News Editor at Energy Daily News -- Data detailed on Energy - Renewable Energy have been presented. According to news originating from Monastir, Tunisia, by NewsRx correspondents, research stated, “This article is interested in a controlled three-phased voltage source inverter (VSI) for a grid-connected wind power generator. The objective consists of participating in auxiliary services by enhancing the grid stability.”

Our news journalists obtained a quote from the research from the University of Monastir, “An active wind generator associated with a battery/super-capacitor storage system composes the studied renewable generator. It is related to a power consumer (load) to form a microgrid (MG) that can work according to grid stability in two modes: standalone and grid-tied. Thus, the principal objective of this study is to develop a robust control method for MG connection with the grid to ensure the grid voltage and frequency regulation. This control has two control tasks: First, an adaptive droop control is implemented to adjust power flows exchanged with the grid to ensure its stability. It regulates its voltage and frequency. Second, a sliding mode control (SMC) with super-twisting algorithm is put forward for the VSI to improve the regulation of the grid voltage and frequency under uncertainties. It improves control results concerning the reduction of harmonics caused by sudden variations of the load and of powers exchanged with the grid. It allows preventing the phenomenon of chattering created by classical sliding mode technique. Extensive simulation studies are carried out under MATLAB/Simulink.”

According to the news editors, the research concluded: “They prove the effectiveness of the suggested droop and SMCs compared with the classical proportional-integral controller.”
